OVERVIEW

Miller AccuLock MDX 1/2" Flush Copper Nozzle (5-Pack)

The Miller AccuLock MDX Nozzle (PN-M1200C) is a premium consumable designed exclusively for the MDX-100 MIG Gun series. Engineered to meet the rigorous demands of modern welding applications, this nozzle features a 1/2-inch bore diameter and a flush tip alignment. The AccuLock MDX system is renowned for its ability to center the contact tip within the nozzle, ensuring concentricity that promotes consistent gas flow and reduces the likelihood of burn-back. This specific nozzle is constructed from high-grade copper, which offers excellent thermal conductivity and durability, making it suitable for a wide range of standard welding tasks.

The flush design of this nozzle is particularly advantageous for welders requiring a balance between gas coverage and stick-out management. By positioning the contact tip flush with the nozzle exit, the operator gains improved visibility of the arc and puddle compared to recessed nozzles, while still maintaining adequate shielding gas protection. This configuration is often preferred for short-circuit MIG welding where control and precision are paramount. The copper material withstands high heat inputs, prolonging the lifespan of the consumable and reducing downtime associated with frequent replacements.

Compatibility is key with the AccuLock system. These nozzles are designed to mate perfectly with the MDX-100 gun diffusers and contact tips, creating a tight seal that prevents gas leakage and air aspiration. This 5-pack configuration ensures that professional fabricators and hobbyists alike have a ready supply of essential consumables on hand. Whether used in automotive repair, light fabrication, or maintenance operations, the PN-M1200C nozzle delivers the reliability expected from Miller Electric products.
